Well here's an example of how it's done, in case you decide you want to do it at a later date. It's just a simple way to double your Reservoir capacity and give you more time away.I’m just running contained units no extra rez. Didn’t have the extra money to shell out for anything else beside what I got lol. I was just trying to be a cheep ass tell I get a grow or two under my belt. I would love to learn your set up but Idk if I’ll have the time or money to set anything new up with what I have already
You use a hole saw to drill a two and a half inch hole in the bottom of two of your buckets.
Then you buy a one and a half inch uniseal for each bucket. Clean up the bucket around the hole you just drilled shove the uniseal in.
Then just put a length of inch and a quarter PVC between the two and drop a AirStone in your second bucket. That's it you're good to go.
